Otis OVF ZA

High quality drive unit for the MCS220 controller built around the Ziehl-Abegg 2CF/2SY elevator drive. This variant of the drive is clearly designed and built for Otis and features custom firmware to allow the standard DSP to interface with Otis' controller. It is not possible to retrofit the OVF ZA with the standard 2CF or 2SY.
